[0002] The rotor in the rotary jet pump is a shell that wraps the water body. The water body rotates with the rotor, and the contact area between the water body and the stationary surface is reduced. Only the dynamic and static contact surfaces between the water body and the collecting pipe are left in the working area. Therefore, the disc friction loss is much smaller than that of conventional centrifugal pumps, and the efficiency is significantly higher than that of centrifugal pumps under the same working conditions in low specific speed situations.

[0003] At present, before the vertical rotary jet pump commonly used in the prior art is started, there is air in the drum, which is not convenient to discharge quickly, so that the drum often vibrates due to the presence of this part of air during operation, and when the rotary jet pump needs to be shut down and restarted for a short time, it needs to be shut down directly. The frequent start and stop of the rotary jet pump causes changes in its internal water vapor environment, which can easily cause damage to the rotary jet pump. In order to reduce the entry of impurities during the water intake process, the rotary jet pump can filter the water through a filter. However, after long-term use, the filter is very easy to be blocked, affecting the water intake capacity of the rotary jet pump.

The water delivery cavity 2025 is provided with a plurality of water outlets 2026. A cam 2021 is fixedly installed on the water delivery cavity 2025. 5 is fixedly connected with a plurality of spiral sheets 2022, one side of the water delivery chamber 2025 is connected with a spray pipe 2028, a spray head is provided on the spray pipe 2028, and the spray pipe 2028 corresponds to the filter screen 1043, a brush 2029 is fixedly connected below the spray pipe 2028, and the brush 2029 is mounted on the filter screen 1043, and the other side of the water delivery chamber 2025 is rotatably mounted on one end of the three-way valve 1013 through a bearing, and the water delivery chamber 2025 is connected with one end of the three-way valve 1013.

[0028] In this embodiment: the water supply operation is carried out by opening the water inlet pipe 1051. At this time, the three-way valve 1013 remains connected to the water delivery chamber 2025, and the water delivery component 101 can deliver water into the tank body 1041 and draw it out through the tank body 1041, so that water circulation can be realized, and the water circulation process is discharged through the water delivery chamber 2025, so that the liquid passes through the spiral piece 2022, and the liquid is sprayed into the liquid by high pressure, so that the water pressure controls the spiral piece 2022 to rotate, and the spiral piece 2022 drives the water delivery chamber 2025 to rotate, and the water delivery chamber 2025 can drive the torsion spring 2032 to twist, and the water delivery chamber 2025 drives the brush 2029 and the spray pipe 2028 to rotate, and the liquid is sprayed out through the nozzle of the spray pipe 2028 at high pressure, so that the high-pressure spray force of the water circulation can improve the cleaning effect of the filter screen 1043 and improve the water intake capacity of the water outlet chamber 1042.

[0029] Working principle: When delivering water, the pump body 1011 is operated to pump water through the water outlet chamber 1042, so that the liquid is delivered through the water delivery pipe 1012, and the water is delivered outward through the upper interface of the three-way valve 1013. As the water level inside the tank body 1041 decreases, the sealing plug 1061 moves downward with the liquid level, and the sealing plug 1061 also pulls the rope 1062 to move, and the rope 1062 pulls the slide rail 1067 to move upward, and the slide rail 1067 drives the first spring 1066 to deform, so that the slide rail 1067 drives the ball 1067 to move upward. 68 slides upward in the linear groove 1034. When the ball 1068 slides to the top of the linear groove 1034 and enters the arc groove 1033, the ball 1068 controls the rotation of the roller 1031 through the arc surface of the arc groove 1033, so that the ball 1068 enters another linear groove 1034. During the rotation process of the roller 1031, the roller 1031 drives the gear 1032 to rotate, and the gear 1032 drives the gear valve 1052. The gear valve 1052 opens the water inlet pipe 1051. At this time, water can be injected through the water source through the water inlet pipe 1051. During the downward movement of the piston 2011, the rope 2033 is loosened. At this time, the torsion spring 2032 releases the torque to drive the water delivery chamber 2025 to rotate. The water delivery chamber 2025 drives the spray pipe 2028 and the brush 2029 to rotate. The brush 2029 rotates to clean the filter 1043. The rotation of the water delivery chamber 2025 drives the cam 2021 to rotate. The convex surface of the cam 2021 squeezes the roller 2015 to move. The roller 2015 drives the connecting rod 2012 and the piston 2011 to move downward, so that the piston 2011 drives the second spring 2013 to deform. When the cam 2021 The convex surface of the piston 2011 is away from the roller 2015, so that the second spring 2013 drives the piston 2011 to reset upward, until the cam 2021 squeezes the roller 2015 again, so that the second spring 2013 can cooperate with the cam 2021 to realize the up and down movement of the piston 2011, so that the up and down movement of the piston 2011 can be used to guide water through the one-way valve 2014, and the piston 2011 can also be discharged through the two-way one-way pipe 2017, and discharged into the water delivery cavity 2025 through the water guide pipe 2018 and the water outlet 2026, and sprayed out through the nozzle of the spray pipe 2028 to clean the filter 1043; After the water inlet pipe 1051 is opened, the upper interface is closed through the three-way valve 1013. At this time, the pump body 1011 continues to extract liquid from the tank body 1041 and inputs it into the water delivery chamber 2025 through the three-way valve 1013, so that the liquid is sprayed out through the nozzle of the spray pipe 2028 to clean the filter screen 1043. In addition, the high-pressure water pressure can drive the spiral piece 2022 to rotate, and the spiral piece 2022 drives the water delivery chamber 2025 to rotate. The water delivery chamber 2025 drives the spray pipe 2028 and the brush 2029 to rotate to further clean the filter screen 1043. When the liquid level inside the tank body 1041 rises, the sealing plug 1061 moves upward, so that the sealing plug 1061 pulls the rope 2033 to move, and the rope 2033 drives the torsion spring 2032 to store elastic potential energy through the rope drum 2031. At this time, the rope 1062 is loose, and the first spring 1066 drives the slide rail 1067 to reset downward, so that the slide rail 1067 drives the ball 1068 to move downward along the linear groove 1034. When the ball 1068 enters the arc groove 1033 below, the roller 1031 rotates and drives the gear 1032 and the tooth valve 1052 to transmit, so that the water inlet pipe 1051 is closed, and at the same time the three-way valve 1013 closes the connection with the water delivery chamber 2025, so that the upper interface of the three-way valve 1013 is opened, and the water delivery operation is realized again.
